Atlantis Submarines offers a one-of-a-kind underwater experience off the shorelines of Oahu, Maui, and Hawaii Island, giving guests a close-up view of an array of marine life, exotic tropical reefs and numerous sunken vessels. It's like swimming in a giant aquarium, but staying dry the whole time! Enjoy your underwater adventure in the comfort and safety of a spacious air-conditioned, Coast Guard approved submarine. Our battery powered vessels are designed and built with your safety and the environment in mind.
